Rob said: “We spent shed-loads of money, adapting the home, going on trips, you name it. People advised me to just give her whatever she wanted while she could still enjoy it — but she never even had dementia.”

Jackie, of Hull, first went to a doctor after her behaviour started to become erratic.

A CT scan at Hull Royal Infirmary led to neurologists giving the verdict of frontal temporal dementia.

But 345 days later, another scan at the hospital revealed she did not have the illness.

Rob, who retired early to look after her, received an apology but is still furious. He added: “We were handed a death sentence. They said she had about five to seven years left.

“I was speaking to a different neurologist who said this is the biggest mistake he has ever heard about.

“In the apology letter, there are 24 excuses but not a reason why this happened.

“But if I sue the NHS, then that might be another incubator not on a ward — and a kid who wouldn’t have a fighting chance."

TOTAL RECALL

COLD SHOWERS

A letter sent to the couple read: "Dr Ming has concluded that there appears to be an incorrect diagnosis made.

"He has outlined that one of the causes of memory and mood changes is severe anxiety and depression disorders, which gives rise to 'pseudo dementia'."

A spokeswoman for Hull and East Yorkshire Hospitals NHS Trust said: “A full investigation into the care received by Jacqueline Dibb was conducted last year and concluded in January 2018. The subsequent outcome letter sent to Mr and Mrs Dibb acknowledged that a misdiagnosis had been made and, in line with the Duty of Candour, an apology was provided.

“Our doctors deny having given Mrs Dibb any timeframe around life expectancy following the dementia diagnosis or discussed end of life, and consider the couple’s claims to be exaggerated.

“They also refute having discussed the progression of the condition she was believed to have in the way Mr and Mrs Dibb describe, and feel they have been misquoted.”
